SPRAYINGr-COIVIPOTIND MIXER.

Specification ot Letters Patent.

Patented Aue. 20, 1912.

Application filed April 6, 1912. Serial No. 688,941.

i following is a specification.`

My invention relates"v to improvements in devices for mixing spraying compounds, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invent-ion is to .provide a device in which substances such as'sulfur and lime may be 'mixed with water so as to insure the. production of a'homogeneous substance.

A further object of my invention is to provide a device which will automatically mix the ingredients of the spraying solution, said device being provided with arms or Scrapers which tend to scrape the solid portions of the mixture toward the central partl ofthe device. thereby preventing:r the clogging of the device.

A further objectof my invent-ion is to provide means by which the larger solid portions of the mixture lmay be broken up.

A further object of my invention 1s t0 provide a device havingT a series of scrapers. certain of sa'id Scrapers having a raking` movement with means for adpisting the movements and positions of the scrapers.

Other objects and advantages will ap pear in the following specification, and .the novel features of the device will be particularly'pointed out in the appended claims.

My invention is illustrated in the aecompanying drawings forming part ot this application in Whichv `Figure 1 is a vertical vsectional view through the device. Fig.'2 is an enlarged A planview ot'-one of the tanks. and Fig. 3

a sectional vierialong; the line 3-3 of Fig. 2. ,Y f

In carryingl out my invention I provide aV longitudinal tank 1, preferabiy madepot metalwhich is disposed above t ."r'nntius tion ch .iber ci V the furnace is connected 1 i.....-. ai to a cnam ei o onde tanti It -ehaniber 'l mi cured `to the 4inner portion of the tank and tank l, and is connected with the latter by means of an inclined pipe S, which is provided with a valve 9. l, l

The .details of the main n 'Xing tank v1 are best shown in Figs. 2 and 3. It will be seen that the tank is provided at each end with a bearing l10. A description of one ot' these bearings will suffice, since they ait` both alike.v They consist of blocks I0 provided with a semi-cylindrical bearing portion b arranged to receive a rod 11. lThe vrod is kept in position by means ot' a plate 10, which slides above the rod..but beneath four lugs such as that shown at 10d. The plate is limited in its movement by a stop member 10 at one end of the block 10. A bolt 10t secures the plate 10C in position. The rod 11 extends through both ends of the device. At one end it is connected by a pivoted rod 12 with a turn buckle 13, the latter being connected by the rod 11 with a slotted-arm 15 on the end ot the crank arm 16.

Referring now more particularly to Fig. L). it'will be seen that I have provided a frame consistingi of thelongitudinal mem# bers 1T md the cross strips 1S underneath the members 1T. The latter are formed of angle irons and are tapered at their ends as shown at 1Sx in Fig. S. These'cross strips servx a double purpose in that they form part of the frame and act as scrapers in a manner hereinafter ydescribed. Secured to the longitudimil members .ITat each end thereof are thc uprights 19. these uprights are adjustable longitudinally of the strips 1 7, and for this purpose the base member 19% of theuprights 19 is slotted. asshown at l9 and bolts 19* pass .through the slots into the members 1T. v

At each cud of the device is a 'pivoted trame consistingr ot' the arms 20. whichare pivoted to the .uprights 19 aud are'bentA downwardly at their ends. as shown in Fig. l. To these arms are secured sideA members 2l and 22. f The side members on opposite sides ofthe tank. areconnected together .by meansot a rod 213. as shown inv Fig. if scraper il Vis carried by the arms 20.

Near the ends ot the tank on cach side 'coiE a blockor plate '25. which is to nhich is pivotally secured .an arm 2b de- L:i t-iigoi'cst normally infan inclinechposi--.

" tion upon :csic-p T tseeiFig. 2)'. 'Between die pivot ot' the arm 26 and the end of tip tank, the block or plate '25 is curved outwardly, as shown at, There/are fourI of these blocks or plates, as shown in Fig. 2. Secured to the v4centralcrossmembers or Scrapers' 1 8fiS ttholl'ow -casting 28, which is corrugated'atv 28fo'n itsexterior side r tions. The castingv is slotted at 28'.' (see gig. 1)y to ermit theentran'ce of'b'olts 29, these Vbolts aving platesf30 [corrugated to ,mesh with the corrugationsof the casting 28.- The rod` 11 has a-downwardly extending arm 31, which `is suitably braced at 32, this arm extending bet-ween the two bolts 29, asshovvn. f From the foregoing description of the various parts of the device, the operation thereo may :be readily,V understood. The water vfor the mixture is heatedin the tank 6 from whence` itma be drawn into the tank lthrough the plpe- 8. The lime and sulfur together with the hot water are placed inthe tank 1, the coverawhich 1s sus. pended by the cable is let down, and the apparatus is started. The revolution of thef crank` A16, 'which is `secured to the engine shaft,(not shown) causes the reci rocation of the rod 11 and of the arm y31,. n Fig..1,

the .'rodis illustrated as movi -towardthe right 'of the figure. As the en s of the rod 23 engage the inclined arms26, the frame ,bearing the scraper`24 is raised. The'far'- ther the rod is pushed oward the `ri ht, the higher the scraper is 4 aised, since t e ends of the rod `23 haveto ride up the linclined pliine. iVheuf the rod 2% reaches the'end of the arm 26, it suddenly drops o', thereby rmittin the scraper 24 to descend to the bieittom: he `rod 23 atthe opposite endof the device will ride under its arm, liftingthe latter' from its stop vpin 27, so that the scra r will remain on the bottom as long as tli4 stroke is ltoward .the "center ol' the tank. When 'the strokeis reversed, however, it will ride up the inclined armv while the rod 23 at the right of the figure will ride underneath its arm 26. This imparts a rak-l ingfmotion' to the scrapers24 and' tends to constantly pull the lime and sulfur away. from the ends and toward the center. The other Scrapers merely move backward and forward along the bottom of the tank.

Thestroke of the scraping device may be varied in a numberof ways. fBy man1 ulating the turn buckle-13, yitis obvious t at the effective length of the' pitman which `connects the arm 15 with the rod l1 maybe lengthene'd or'shortened, thus varyin the stroke. The position of the scraping rame with respect to the arm 31 I may be varied by shifting the bolts 19 along the slotted cast'- ing 28. Moreover byl adjusting the distance between the bolts, the rod 11 may be moved -without necessarily moving the Scrapers.

l nThe pivoted raking members at each end of 'gitudinal members, a series o the scraper device may be adjusted by shift-- ing the uprights 19, which, as stated before,

y 1,oae,saa

4is accomplished by loosening the bolts 19,

and shifting the supports of the uprights 19.

4These adjustments permit of theA regulation sprayingl mixture with Aa minimum amount j of heat, since the cover y34 may be lowered to kee the heat within the tank. If, however, t e heat should rise too fast or too suddenly the vcover may be raised slightly to permit the heat to escape.
